[Moved to DR at the November, 2016 meeting.]

The resolution of issue 1838 was intended to resolve issue 1021 but does not actually do so, as it applies only to declarations with a declarator-id, which is not true of classes and enumerations.

Proposed resolution (October, 2015):

1. Change _N4868_.9.8.2.3 [namespace.memdef] paragraph 1 as follows:

A declaration in a namespace N (excluding declarations in nested scopes) whose declarator-id is an unqualified-id (9.3.4 [dcl.meaning]), whose class-head-name (Clause 11 [class]) or enum-head-name (9.8.1 [dcl.enum]) is an identifier, or whose elaborated-type-specifier is of the form class-key attribute-specifier-seq_opt identifier (9.2.9.5 [dcl.type.elab]), or that is an opaque-enum-declaration, declares (or redeclares) its unqualified-id or identifier as a member of N , and may be a definition. [Note:...

2. Change the grammar of 9.8.1 [dcl.enum] as follows:

enum-head:
enum-key attribute-specifier-seq_opt identifier enum-head-name_opt enum-base_opt
enum-key attribute-specifier-seq_opt nested-name-specifier identifier enum-base_opt
enum-head-name:
nested-name-specifier_opt identifier
